Biological characteristics: The common characteristics of the wide-body golden leech, the brown leech and the Japanese medicine leech are: the body length is slightly flattened, there are suction cups at the front and back ends, and the whole body has 5 ring patterns, each ring has a similar width; Hermaphroditic, the male and female reproductive pores open between the rings and rings of the ventral surface, with the male pores in front and the female in the back; 10 eyes, arranged in shape; All of them use paddy fields, streams and other waters as habitats, and can be used for wave swimming and inchworm migration.

Leeches enter the house through cracks in doors, openings, etc.

Leeches love damp places, your room is too damp, pay attention to ventilation. Anyone who has been bitten by a leech will fall off on its own after it has sucked up its blood.

If you find that it is sucking blood, you must not pull it with your hands to get rid of it. Because it has strong suction and is not easy to pull down, deadlift is not good for wounds. You can slap your hand a few times, or put a few drops of salt water, alcohol, vinegar on the bite site, or burn the leech with a match.

The wound can be washed with boric acid for a few days to prevent infection and suppuration.

Prevention of leeches:

1. Apply with chemicals**. According to foreign reports, drought-based leeches can be prevented by coating ** with repellents such as dimethyl phthalate, mosquito repellent, or insect repellent. In addition, apply it to ** with cedarwood oil or repellent +50 lanolin, which has a certain repellent effect on leeches.

The United States has tried compound repellents in the northern part of Borneo, an island in the South Seas, and it has also had good results.

2. Hainan Island uses the scraps of Guangzhou mosquito repellent to soak cloth strips to prevent leeches, and the control effect of one soaking is 5-7 days. The cloth strip is soaked in the repellent, each dosage is 15 ml, or the repellent ointment is applied to the entire cloth strip on one side, each dosage is 3 grams, the two ends of the cloth strip are sewn into a circular sleeve, and the boot cuff is set on the outside of the rubber boots worn by the staff to form a ring repellent belt to prevent leeches from climbing on the human body to suck blood.

Soaking cloth strips with maleimide dilution of 30 acetone has the best repellent effect, and the repellent time is more than 20 days.

Because leeches generally come out at night and prefer humid places

Under normal circumstances, leeches mostly live in waters containing 0.7 mg of dissolved oxygen, and when they are below a certain degree of dissolved oxygen, leeches will burrow out of the water and crawl into the soil and grass on the shore to breathe oxygen in the air.

Leeches like to live in waters with more stones, the bottom and shore of the pond are relatively hard, and aquatic weeds and algae are rich, which is not only conducive to the fixation, movement and feeding of leech suckers, but also conducive to the concealment and habitat of leeches.

Wild leeches are most abundant in reservoirs, ditches, paddy fields, lakes and marshes in freshwater, in ponds with abundant organic matter or in unpolluted small rivers.

Leeches live in rice fields, ditches, shallow water polluted pits and ponds, etc., love to suck the blood of humans and animals, move very quickly, can swim in waves, and can also move in the form of inchworms. It is active every spring and warm, and its spawning period is from June to October, and it often lies dormant in the coastal wet mud in winter, without food or movement, and has strong survival ability. Leeches feed on the blood or body fluids of animals as their main way of life, and often use plankton, insects, and mollusks in the water as their main bait.

Appearance characteristics of leeches:

The body length is slightly flattened, at first glance it looks cylindrical, the body is about 2 15 cm long and 2 mm wide. The dorsal surface is green with black in the middle, with 5 yellow longitudinal lines, the ventral surface is flat, grayish-green, without variegated spots, the overall annular pattern is prominent, and the body segment is composed of 5 rings, each with a similar width. 10 eyes, arranged in the shape of the envy wheel, there are 3 semicircular jaws in the mouth to form a Y shape, when sucking the animal body, use this jaw to drill into **, the body is large, the body length is 60-120mm, the width is 13-14mm.

The back is dark green, with 5 longitudinal lines, which draws blood and stores it through the esophagus through the pharynx in the entire digestive tract and blind sac. The defeated annihilators have excretory holes in each segment of the body, and the opening is ventral. The male and female reproductive pores are separated by 4 rings, and each opening is between the rings.
